Owned by two Jewish immigrants dubbed the “Shirtwaist Kings,” the Triangle Shirtwaist Factory was located on the top three floors of the Asch Building on Washington Place. More than 500 workers labored here long hours, six days a week. Late in the afternoon of Saturday, March 25, 1911, a fire started on the eighth floor. Flames soon engulfed the entire factory. Within a half hour, 146 workers, over half of them Jewish women, were dead.
